FAQ
Common Client Questions
Detailed answers about data quality, security, delivery timelines, and more.
How do you guarantee data accuracy? What happens if there is a quality issue?
We ensure data quality through our three-tier QC system (self-check → peer-check → expert-check), consistently achieving 99.2%+ accuracy. Every batch is delivered with a quality report and supports random sampling verification by the client. If non-conforming data is found during acceptance, we commit to free rework within the agreed timeframe until the quality standard is met. For long-term partnerships, we also provide ongoing quality tracking and optimization services.
How is data security guaranteed? Will our data be leaked?
Data security is our most critical commitment. All employees sign strict NDAs. Data is processed in encrypted environments, and no storage devices are allowed in work areas. Our annotation platform supports private deployment — client data can be processed entirely on the client's own servers. When projects complete, all local data is destroyed per agreement with destruction certificates provided.
What is the typical delivery timeline? Can you support urgent projects?
Standard projects take 3–7 business days from specification to first delivery (including pilot validation). Batch output averages around 100K items per day depending on complexity, and we can scale resources to client deadlines. For urgent projects, we can start within 24 hours by expanding team size and extending working hours.
Which delivery formats are supported? Can you deliver in our proprietary format?
We support all mainstream annotation formats including COCO JSON, Pascal VOC XML, YOLO TXT, LabelMe JSON, CSV — over 10 formats with one-click export. If your team requires a proprietary format, our technical team can develop a custom adapter during project initialization, usually within 1–2 business days. We also support direct API integration with your training platform.
Can we start with a small batch? What is the minimum order?
There is no strict minimum order requirement. For early-stage exploration, we offer pilot labeling services (typically from 500–1000 items) so you can validate feasibility before scaling. For large-scale long-term projects, we offer dedicated pricing and priority resource allocation.
How do we start working together? What is the process?
The collaboration process is simple: (1) Fill out the inquiry form or call our business hotline to describe your needs. (2) A project manager contacts you within 24 hours for detailed discussion. (3) We deliver a proposal and quote within 1–2 business days. (4) After approval and contract signing, the project kicks off. For first-time engagements, we schedule a pilot batch to verify satisfaction before moving into full production. A dedicated PM stays with you throughout the entire process.
